Letters 'Patent No. 101,484, dated April 5, 1870.

WATER-ELEVATOR.

The Schedule referred to' in these Letters Patent and making part or thesame My Ainvention has for its object to furnish an improved apparatns,by means of which the heat necessarily generated in every household maybe used for raisingwater from a. well or cstern to a reservoir or tankat any desired elevation, from which the said water may be withdrawn asrequired; and

It consists in the construction and combination of the various parts ofthe apparatus, as hereinafter more fully described.

.A is a close cylindrical vessel, made of suitable material and ofsudicientstrength to resist a pressure of about iteen pounds to thesquare inc-h.

B is a 'close vessel made of copper, placed in the lower part of thecylinder A, and connected with its sides by the inlet-pipe C and theoutlet pipe D.

The pipe C leads from the vessel B to the upper compartment of thevessel E.

The vessl E is divided into two compartments by the partition e',through which partition there is an opening, in 'which is placed avalve, F, opening upward. l

Gis a pipe leading from the upper compartment of the vessel E to thetank or receiver, into'which the water is to be raised.

H isa. pipe leadingti'om an opening in the bottom ofthe vessel Eto thewell or cistern from which the water is to be raised.

The opening in the bottom of the vessel E leading into the pipe H isprovided with a valve, I, opening upward.

J is a pipe leading from the lower compartment of the vessel E t0 theupper part of the cylinder A, as shown in the drawing. l

K is a piston, fitting into and moving up and down in the cylinder Aabove the vessel B.

L is the piston-rod, which' projects through a hole in the top ofthecylinder A.'

M is a valve placed in the pipe C near the cylinder A, and to thecrank-handle of which is pivoted the lower end of the connecting-rod N,the upper end of v which is pivoted to the outer endof the lever O,which is pivoted to a standard, P, attached to the cylinder A in such aposition that the inner end of the lever O may project over the middlepart of the top of the cylinder A, so that as the piston K rises to thetop of the said cylinder, the upper end of the piston-rod may strikeagainst and raise the inner end of the said lev'er O, opening the valveM.

In using the apparatus, the cylinder A is placed upon a stove or otherheat-generating furnace. The space around the vessel B in the lower part0f the cylinder A, below the piston K, is filled with water through-thepipe R, and the stop-cock S is closed.

Enough water is then poured into the tank or receiver, into which thewater is to berraised, 'to lill the pipes C and G, leaving a few gallonsstill in said tank.

As the water below the piston K heats up, steam is generated and raisesthe piston, forcing the air out of the upper part'of the cylinder A,through the pipe J into the lower compartment of the vessel E, fromwhich it escapes through the valve F and pipe G.

As the piston K reaches the top of the cylinder A, the lever O isoperated and the valve M opened, allowing the water from the pipes G andG to ow into and through the vessel B, 'condensing the steam in thecylinder A, and causing the piston K to descend, releasing the lever O,which is immediately operatedby the weight Q, to close the valve M. l

As the piston K descends, a vacuum is formed in the upper part ot' thecylinder A, pipe J, and lower compartment of the vessel E.

The pressure of the air upon the water in the well or cistern from whichtheewater is to be raised now forces the water up through the pipe H andvalve I into the lower compartment of the vessel E, from which it flowsthrough the pipe J, into the upper part of the cylinder A.

As the piston K again rises, the water above it is forced through thepipe J, and valve F and pipe G, into the receiver or tank, and so on aslong as the heat is kept up.

Having thus described my invention,

What I claim as'new, anddesire to secure by Letters Patent, is l Thecombination of lthe cylinder A, vessel B, pipes C G H J, vessel E e',valves F I, piston K, piston-rod L, weighted lever O, connecting-rod N,and valve M with, each other, substantially `as herein shown anddescribed, and for the purpose set forth.
